IUGG Structure

IUGG Associations, Inter-Association Activities, Union Commissions, and Working Groups encourage scientific investigation of Earth science and especially interdisciplinary aspects. Each Association establishes working groups and commissions that can be accessed by using the links below or at the top of this page.

Countries in which "independent activity in geodesy and geophysics has been developed" may establish an Adhering Organization/Body and seek membership. For more information, visit How to Join or About IUGG.
